KMX

MINIATURE -105C

KMX Series

The KMX is a long life, low impedance series from United Chemi-Con. These capacitors have a load

life of 8,000 to 10,000 hours at 

105C with the full rated ripple current applied and a voltage range

from 160 to 450 volts. The KMX capacitors are ideal for use in electronic ballasts or any other high

voltage application where a very long lifetime is required. The KMX series capacitors are available in

slender case sizes with 10 to 18mm diameters and 20 to 60mm lengths.

The KMX series capacitors are non-solvent proof. Refer to the Mini-Glossary for cleaning guidelines

and recommended cleaning agents that are compatible with United Chemi-Con products.
